3 Claims.

This invention is a dust collector for dry mop which also serves as a storage housing when the mop is not in use. The dust is removed by a rotary motion of the mop during which the mop head strikes against ribs or bars which dislodge the dust. The rotary motion is facilitated by a crank attached to the end of the mop handle. During storage, the mop handle is held in an upright position in a channel at the front of the collector housing. Further objects and advantages appear in the specification and claims.

In the drawing, Fig. 1 is a top view of the dust collector; Fig. 2 is a front view showing the mop in the storage position; Fig. 3 is a side view showing the mop in the dust-removing position; Fig. 4 is a sectional plan view on line 44 of Fig. 2 with the cover open showing the ribs and bars for dislodging the dust; and Fig. 5 is a detail showing the removable support for the grille.

Referring to the drawing, there is shown a casing having front and back walls I and 2, end walls 3, and a top wall 4. Access to the casing is provided by a closure or cover 5 hinged at 6 to the top wall 4. The cover has a wall I, which forms a continuation of the top wall 4 and a wall 8 which overlaps the front wall I of the casing. Between the hinges 6 is located a handle 9 by which the casing may be conveniently carried.

In the front wall 8 of the cover 5 is a vertical open ended channel I for receiving a mop handle H in an upright storage position as shown in Fig. 2. A clip l2 fastened on the wall 1 provides detent for yieldably holding the mop handle in the upright position. At the lower end of the channel H3 is an opening into the casing formed by a semi-circular bearing I3 in the upper edge of the front casing wall I and the complementary lower end of the channel E0. The bearing I3 serves as a support for the mop handle when it is swung to the horiozntal shaking position shown in Fig. 3. The mop handle is pivoted at M to a mop head l which may be of conventional shape. In the shaking position, a crank it pivoted to the upper end of the mop handle is swung to the operating position shown in Fig. 3 so that the mop handle may be rotated. During the rotation, the fringe 11 or dust collecting elements of the mop head slide freely over the smooth surface of the back wall 2 of the casing and strike against diagonal intersecting ribs 18 on the back wall of the casing 2 and also against bars l9 fixed to an arcuate frame 20 having ends 2| resting in hooks 22 on the inner surfaces of the casing end walls 3. The frame 20, together with the bars l9,

forms a grille through which the dust dislodged from the mop head freely flows into a dust collecting zone 23 at the bottom of the casing. The spacing of the bars l9 from the bearing [3 is such that the fringe or dust collecting elements of the mop head strike against the bars as the mop handle is rotated. The force of impact is determined by the speed of rotation of the mop handle. It is important that the bars occupy only a part of the space around the mop head so the fringe will have a chance to move outward prior to striking the bars.

In the use of the dust collector, the cover 5 is lifted thereby opening the top front wall of the casing so the mop head can be inserted with the mop handle in a horizontal position and resting in the bearing I3. The cover 5 is then closed and the crank 16, which is normally folded over the end of the handle as indicated in Fig. 2, is swung out into the operating position. A few turns of the mop handle will usually sufice to dislodge the dust, due to the positive centrifugal impact of the fringe with the dust dislodging ribs or bars 19. It is usually advisable to wait a short interval before opening the cover 'so as to permit the settling of dust within the casing. If the mop is to be stored, the handle is swung to the upright position within the channel In and the crank l6 folded over the upper end of the handle. In this position, the casing serves as a convenient storage unit for the mop.

The accumulated dust in the bottom of the casing can be removed by opening the cover 5, removing the mop and grille, and emptying the contents.

What I claim as new is:

1. A dust collector for dry mops, comprising a casing for receiving a mop head having a vertical channel facing the outside of the casing and recessed into an outer wall of the same and extending from the top toward the bottom of the casing, the lower end of the channel being open and leading into the interior of the casing behind said outer wall and the upper end of the channel being open whereby a mop handle may be received in the channel with the mop head lying within the casing and the upper end of the handle projecting out of the channel, said outer wall having an opening at the lower end of the channel into which the mop handle may be swung to a horizontal position with the head within the casing, a grille in the casing arranged to be struck by the mop head as the handle is twirled, and closure means for an opening to the casing through which the mop head may be inserted into the casing and the handle into said opening at the lower end of the channel.

2. A dust collector for dry mops, comprising a casing for receiving a mop head having a vertical channel facing the outside of the casing and recessed into an outer wall of the same and extending from the top toward the bottom of the casing, the lower end of the channel being open and leading into the interior of the casing behind said outer wall and the upper end of the channel being open whereby a mop handle may be received in the channel with the mop head lying within the casing and the upper end of the handle projecting out of the channel; said outer wall having an opening at the lower end of the channel into which the mop handle may be swung to a horizontal position with the head Within the casing, a grille in the lower partof the casing arranged to be struck by themop head as the handle is twirled, the grille occupying only part of the space around the mop head so the fringe of the mop head is extended prior to striking the grille, and closure means for an opening to the casing through which the mop head may be inserted into the casing and the handle into said opening at the lower end of the channel.

3. A dust collector for dry mops, comprising a casing for receiving a mop head, a hinged cover for the casing, said cover having a wall comprising part of the front wall of the casing in the closed position, a vertical channel recessed in said cover wall facing the outside of the casing and extending from the top toward the bottom of the casing, the lower end of the channel being open and leading into the interior of the casing behind the front wall of the casing and the upper end of the channel being open whereby a mop handle may be received in the channel with the mop head lying within the casing and the upper end of the handle projecting out of the channel, and said front wall of the casing having a horizontal opening at the lower end of the channel into which the mop handle may be swung to a horizontal position with the head within the c-as ing in which the mop handle may be twirled to dislodge dust from the head.
